(c) Vektor kedudukan sebuah dron \( A, t \) saat selepas meninggalkan tempat berlepas ialah \( t\binom{30}{15} \) manakala vektor kedudukan dron \( B \) ialah \( \binom{50}{5}+t\binom{10}{10} \). Tentukan halaju bagi dron \( A \) dan dron \( B \). Adakah dron \( A \) dan dron \( B \) akan bertembung? The position vector of a drone \( A, t \) seconds after leaving the takeoff point is \( t\binom{30}{15} \) while the position vector of drone \( B \) is \( \left(\frac{50}{5}\right)+t\binom{10}{10} \). Determine the velocity of drone \( A \) and drone \( B \). Will drone \( A \) and drone \( B \) collide?

A sensitive galvanometer, the maximum curent that its coil can measure is \( 5 \mathrm{~m} / \), and when it is used to measure an electne current of intensity \( 2 \times 10^{\prime} 1 \mathrm{LA} \) its pointer deflects by an angle \( 30^{\circ} \), so the maximum angle of deflection of the galvanometer pointer from zero position is .......... (A) \( 25^{\circ} \) (B) \( 50^{\circ} \) (C) \( 75^{\circ} \) (D) \( 90^{\circ} \)

5. Su una portaerei un jet viene catapultato da \( 0 \mathrm{~km} / \mathrm{h} \) a \( 240 \mathrm{~km} / \mathrm{h} \) in \( 2,00 \mathrm{~s} \). Se la forza media esercitata dalla catapulta è \( 9,35 \cdot 10^{5} \mathrm{~N} \), qual è la massa del jet?

A struight wire of length \( \left(\pi^{\prime}\right) \) meter is carrying a current of \( 2 \Lambda \) and the magnetic field at a point of distence lcm from it is ( \( B_{1} \) ). If the wire is bent into a ring end carrying the same current as before, the ratio of the magnetic field (B) at its center to that oblained in the first case \( \left(B_{1}\right) \) would be: (A) 1:100 (B) \( 100: 1 \) (C) \( 1: 50 \) (D) \( 50: 1 \)
